Location based reminders

ABSTRACT

Location based reminders are described. A mobile computing device may comprise a location based reminder application to set a target location for a reminder item. The location based reminder application may provide a location based reminder for the reminder item when a current location matches the target location. Other embodiments may be described and claimed.

BACKGROUND

A mobile computing device such as a smart phone may have voice and data communications capabilities as well as processing capabilities. The processing capabilities may allow a mobile computing device to store and execute a number of application programs, such as a personal information manager (PIM) application, for example. A PIM application may comprise a software application arranged to organize personal information for a user, such as a contact manager to manage contact information for multiple entities, a calendar manager to manage events, a task manager to manage tasks, a memo manager to manage memos, an email manager to manage email, and so forth. Typically the PIM application allows a user to set reminders for various events, tasks, memos, and emails. The reminders, however, are typically limited to a date and/or time, and therefore may not take advantage of the additional resources potentially provided by a mobile computing device.

DETAILED DESCRIPTION

Various embodiments may be generally directed to techniques for providing automatic reminders based on location of a mobile computing device. In one embodiment, for example, a mobile computing device such as a smart phone may comprise a location based reminder application and a location device. The location based reminder application may trigger reminders based on a location of the mobile computing device. For example, the location based reminder application may be used to set a target location for a reminder item. Examples of target locations may include any defined physical location, such as a location for a residence, commercial office, school, store, and so forth. Examples of reminder items may include any defined item suitable for reminders, such as calendar events, tasks, memos, emails, instant messages, and so forth. The location based reminder application may provide a location based reminder for the reminder item when a current location matches the target location. The current location may be determined by the location device, such as a global positioning system (GPS) or other location identifying device or system. In this manner, a user may be automatically reminded of a reminder item based on a location. In addition to providing location based reminders, the location based reminder application may be used with other reminder triggers, such as a date and/or time. Other embodiments may be described and claimed.

In addition to voice communication services, mobile computing device 110 and wireless device 120 may be arranged to perform data communications using any number of different wireless protocols over wireless shared media 122-1. In one embodiment, for example, mobile computing device 110 and wireless device 120 may be arranged to perform data communications using any number of different WWAN data communication services. Examples of cellular data communication systems offering WWAN data communication services may include GSM with General Packet Radio Service (GPRS) systems (GSM/GPRS), CDMA/1xRTT systems, Enhanced Data Rates for Global Evolution (EDGE) systems, Evolution Data Only or Evolution Data Optimized (EV-DO) systems, Evolution For Data and Voice (EV-DV) systems, High Speed Downlink Packet Access (HSDPA) systems, and so forth. In one embodiment, for example, mobile computing device 110 and wireless device 120 may also be arranged to communicate using a number of different WLAN data communication services. Examples of suitable WLAN data communication services may include the Institute of Electrical and Electronics Engineers (IEEE) 802.xx series of protocols, such as IEEE 802.11a/b/g/n, IEEE 802.16, IEEE 802.20, and so forth. In one embodiment, for example, mobile computing device 110 and wireless device 120 may be further arranged to communicate using a number of shorter range wireless protocols, such as a wireless personal area network (PAN) protocols, an Infrared protocol, a protocol from the Bluetooth Special Interest Group (SIG) series of protocols, including Bluetooth Specification versions v1.0, v1.1, v1.2, v2.0, v2.0 with Enhanced Data Rate (EDR), as well as one or more Bluetooth Profiles, and so forth. Yet another example of wireless protocols may include near-field communication techniques and protocols, such as electro-magnetic induction (EMI) techniques. An example of EMI techniques may include passive or active radio-frequency identification (RFID) protocols and devices. The embodiments are not limited in this respect.

In one embodiment, communications system 100 may include network 130 connected to wireless device 120 by wired communications medium 122-2. Network 130 may comprise additional devices and connections to other networks, including a voice/data network such as the Public Switched Telephone Network (PSTN), a packet network such as the Internet, a local area network (LAN), a metropolitan area network (MAN), a wide area network (WAN), an enterprise network, a private network, and so forth. In one embodiment, for example, network 130 may be arranged to communicate information in accordance with one or more Internet protocols as defined by the Internet Engineering Task Force (IETF), such as the Transmission Control Protocol/Internet Protocol (TCP/IP), for example. Network 130 may also include other cellular radio telephone system infrastructure and equipment, such as base stations, mobile subscriber centers, central offices, and so forth. The embodiments are not limited in this context.

In general operation, mobile computing device 110 may be capable of storing and executing a number of application programs. One example of an application program may include any software capable of generating and setting reminder items, such as a PIM application, for example. A PIM application may comprise a software application arranged to organize personal information for a user, such as a contact manager to manage contact information and/or context information for multiple entities, a calendar manager to manage events, a task manager to manage tasks, a memo manager to manage memos, an email manager to manage email, and so forth.

Typically the PIM application allows a user to set reminders for various reminder items, such as calendar events, tasks, memos, emails, voice mails, instant messages, and so forth. For example, a user may schedule a calendar event such as an appointment or meeting. The user may schedule the calendar event by using a user interface to enter appointment information. Examples of appointment information may include a date, subject information, a start time, an end time, appointment location, and so forth. The appointment location typically includes information such as a conference room for an office where the meeting or appointment is scheduled to take place. The appointment information may further include whether to set a reminder for the appointment, and a defined time period to provide the reminder. The defined period may be in any time dimension, and is typically in minutes, hours, days, weeks, or months. For example, a user may set a location based reminder for 15 minutes before the appointment start time on the day of the appointment. The reminder may serve as a technique for providing notice or reminding a user of the appointment so that the user may prepare and attend the appointment.

Similar reminders may be set for any reminder items available via the PIM application, or any other application or system programs available on mobile computing device 110. For example, mobile computing device 110 may include other application programs such as a memo application, for example. A memo application may manage various types of reminder items in the form of memos or notes for a user. A memo may be created using different types of information, such as voice information, video information, audio information, text information, numerical information, symbols, alphanumeric symbols, graphics, images, computer generated images, pictures, icons, and so forth. The memo application may comprise part of the PIM application, or may be implemented separately, as desired for a given implementation. The embodiments are not limited in this context.

One problem with reminders for a PIM application or other application programs is that the reminders are typically limited to a date and/or time. There may be other hardware or software resources, however, implemented for mobile computing device 110 and available to the PIM application. Conventional reminder techniques may fail to take advantage of these additional resources potentially provided by mobile computing device 110.

In order to solve these and other problems, mobile computing device 110 may use various reminder techniques to manage reminders for various application or system programs for mobile computing device 110 in order to potentially enhance productivity, accessibility, and value to a user. More particularly, mobile computing device 110 may use reminder triggers based on a location for mobile computing device 110. In one embodiment, for example, mobile computing device 110 may include a location based reminder application. The location based reminder application may be used to set a target location for a reminder item. Examples of target locations may include any defined physical location, such as a location for a residence, commercial office, school, store, and so forth. The location based reminder application may provide a location based reminder for the reminder item when a current location matches the target location. The current location may be determined by a GPS or other location identifying system. In this manner, a user may be automatically reminded of reminder item based on a location either alone or in conjunction with other reminder triggers, such as a date and/or time, for example. Mobile computing device 110 in general, and location based reminder application in particular, may be described in more detail with reference to FIGS. 2-6.

The embodiments are not limited in this context.

FIG. 3 illustrates one embodiment a radio sub-system. FIG. 3 illustrates a more detailed block diagram of radio sub-system 202 as described with reference to FIG. 2. Radio sub-system 202 may perform voice and data communication operations for mobile computing device 110. For example, radio sub-system 202 may be arranged to communicate voice information and control information over one or more assigned frequency bands of wireless shared media 122-1. The embodiments are not meant to be limited, however, to the example given in FIG. 3.

In various embodiments, radio sub-system 202 may include one or more antennas 302-1-m. Antennas 302-1-m may be used for transmitting and/or receiving electrical signals. Examples for antennas 302-1-m may include an internal antenna, an omni-directional antenna, a monopole antenna, a dipole antenna, an end fed antenna, a circularly polarized antenna, a micro-strip antenna, a diversity antenna, a dual antenna, an antenna array, a helical antenna, and so forth. During transmission, antennas 302-1-m may accept energy from a transmission line and radiate this energy into space via wireless shared media 122-1. During reception, antennas 302-1-m may gather energy from an incident wave received over wireless shared media 122-1, and provide this energy to a corresponding transmission line. The amount of power radiated from or received by antennas 302-1-m is typically described in terms of gain. Radio sub-system 202 may be implemented using a single antenna 302-1, or using an array of antennas 302-1-m array, such as a quad band antenna array, for example. Multiple antennas may be desirable when implementing spatial diversity and/or Multiple-Input-Multiple-Output (MIMO) systems. The embodiments are not limited in this context.

In various embodiments, antennas 302-1-m may be connected to a multiplexer 304. Multiplexer 304 multiplexes signals from power amplifiers 306-1, 306-2 for delivery to antennas 302-1-m. Multiplexer 304 demultiplexes signals received from antennas 302-1-m for delivery to RF chipset 312. The embodiments are not limited in this context.

In various embodiments, multiplexer 304 may be connected to power amplifiers 306-1, 306-2. Power amplifiers 306-1, 306-2 may be used to amplify any signals to be transmitted over wireless shared media 122-1. Power amplifiers 306-1, 306-2 may work in all assigned frequency bands, such as 4 frequency bands in a quad-band system. Power amplifiers 306-1, 306-2 may also operate in various modulation modes, such as Gaussian Minimum Shift Keying (GSMK) modulation suitable for GSM systems, 8-ary Phase Shift Keying (8-PSK) modulation suitable for EDGE systems, 16 Quadrature Amplitude Module (QAM) and/or Quadrature Phase Shift Keying (QPSK) for HSDPA, and so forth. The embodiments are not limited in this context.

In various embodiments, power amplifiers 306-1, 306-2 may be connected to an RF chipset 312. RF chipset 312 may also be connected to multiplexer 304. In one embodiment, for example, RF chipset 312 may comprise one or more transceivers in a transceiver array. For example, RF chipset 312 may include RF drivers 308-1, 308-2 each coupled to RF transceivers 310-1, 310-2, respectively. RF chipset 312 may perform modulation and direct conversion operations required for GMSK and 8-PSK signal types for quad-band E-GPRS radio, for example. RF chipset 312 receives analog I & Q signals from a baseband processor 314, and converts them to an RF signal suitable for amplification by power amplifiers 306-1, 306-2. Similarly, RF chipset 312 converts the signals received from wireless shared media 122-1 via antennas 302-1-m and multiplexer 304 to analog I & Q signals to be sent to baseband processor 314. RF chipset 312 may be implemented using one or more chips as desired for a given implementation. The embodiments are not limited in this context.

In some embodiments, each transceiver 310-1, 310-2 may be arranged to perform data communications in accordance with a different set of wireless communications protocols and techniques. In one embodiment, for example, transceiver 310-1 may be arranged to communicate information in accordance with a first class of wireless communications protocols and techniques that are generally associated with cellular radiotelephone communication systems. Examples of the first class of protocols may include WWAN protocols, such as GSM/GPRS protocols, CDMA/1xRTT protocols, EDGE protocols, EV-DO protocols, EV-DV protocols, HSDPA protocols, and so forth. In one embodiment, for example, transceiver 310-2 may be arranged to communicate information in accordance with a second class of wireless communications protocols and techniques that are generally associated with a computer network. Examples of the second class of protocols may include WLAN protocols, such as one or more of the IEEE 802.xx series of protocols, such as IEEE 802.11a/b/g/n, IEEE 802.16, IEEE 802.20, and so forth. Other examples of the second class of protocols may include PAN protocols, Infrared protocols, Bluetooth protocols, EMI protocols including passive or active RFID protocols, and so forth. It may be appreciated that although the various protocols have been generally separated into a first class and a second class, it may be appreciated that transceivers 310-1, 310-2 may be arranged to use any type of protocol from either class as desired for a given implementation. It may also be appreciated that although RF chipset 312 is shown with two transceivers 310-1, 310-2 by way of example, RF chipset 312 may be implemented using more or less transceivers as desired for a given implementation. The embodiments are not limited in this respect.

It is worthy to note that some portion or all of memory 406 may be included on the same integrated circuit as processor 402 thereby obviating the need for bus 404. Alternatively some portion or all of memory 406 may be disposed on an integrated circuit or other medium, for example a hard disk drive, that is external to the integrated circuit of processor 402, and processor 402 may access memory 406 via memory bus 404. The embodiments are not limited in this context.

In various embodiments, memory 406 may store one or more software components. A software component may refer to one or more programs, or a portion of a program, used to implement a discrete set of operations. In one embodiment, for example, memory 406 may include one or more software components, such as a location based reminder module (LBRM) 408. LBRM 408 may be responsible for certain location based reminder operations for mobile computing device 110.

As shown in FIG. 5, LBRM 408 includes an OS 502, a location based reminder application (LBRA) 512, a reminder database 514, a PIM application 516, and a location device 518. OS 502 includes an alarm manager 504, an attention manager 506, a user interface 508, and a display interface 510. It may be appreciated that the elements of OS 502 may also be implemented as part of LBRA 512, or LBRA 512 as part of OS 502, or some combination thereof, and such combinations would still fall within the scope of the embodiments.

It is worthy to note that some embodiments may be described using the expression “coupled” and “connected” along with their derivatives. These terms are not intended as synonyms for each other. For example, some embodiments may be described using the terms “connected” and/or “coupled” to indicate that two or more elements are in direct physical or electrical contact with each other. The term “coupled,” however, may also mean that two or more elements are not in direct contact with each other, but yet still co-operate or interact with each other. With respect to software elements, for example, the term “coupled” may refer to interfaces, message interfaces, API, exchanging messages, and so forth.

In various embodiments, LBRM 408 may include reminder database 514. Reminder database 514 may be used to store reminder information, such as various reminder items and corresponding location information, such as target locations, target location names, target location information, and any other desired location information. LBRA 512 and/or PIM application 516 may store reminder information in reminder database 514. Alternatively, LBRA 512 and/or PIM application 516 may store reminder information in other databases, lists, tables, or other data structures, such as part of an existing PIM database, a shared database, a relational database, and so forth.

In various embodiments, LBRM 408 may include LBRA 512 coupled to reminder database 514. LBRA 512 may be arranged to manage reminders for mobile computing device 110. More particularly, LBRA 512 may be arranged to provide location based reminders for reminder items based on a location. The reminder items may be created or generated by any suitable application or system software implemented for mobile computing device 110, such as LBRA 512, PIM application 516, a memo application, and so forth. The reminder items may be created or generated using, for example, one or more of video module 410, audio module 412, and/or text module 414. Consequently, the reminder item may comprise any form of text-based or multimedia-based reminder item. Alternatively, LBRA 512 may receive one or more reminder items from another application, such as one or more components of OS 502, for example.

Once a reminder item has been created, a user may associate or set a target location with the reminder item. The target location may be represented using any suitable type of unique target location name and location information. The location information may refer to any information used to uniquely identify a physical location, such as an address, a map address, latitude coordinates, longitude coordinates, altitude or elevation information, and so forth. The location information may have any desired level of granularity and detail capable of being handled by location device 518 and as desired for a given implementation. LBRA 512 may store the reminder item and corresponding target location name and location information in reminder database 514.

In some embodiments, LBRA 512 may also set a location reminder value for the reminder item as well. The location reminder value may be a status flag used to indicate whether a target location has been stored with the reminder item. For example, the location reminder value may be set to a logical one (1) to indicate that the reminder item has a corresponding target location, a logical zero (0) to indicate that the reminder item does not have a corresponding target location, or vice-versa. LBRA 512 may store the reminder item with the corresponding location reminder value in reminder database 514. LBRA 512 may use the location reminder value to facilitate searches through larger volumes of reminder items to determine whether a sub-set of reminder items have an associated target location. LBRA 512 may then more closely search the sub-set of reminder items during matching operations when determining whether to provide a location based reminder, such as during location matching operations, for example.

In various embodiments, OS 502 of LBRM 408 may be coupled to location device 518. Location device 518 may be arranged to generate current location information for mobile computing device 110. Current location information may include any of the information previously defined for target location information. The specific type of location information used for both the current location information and target location information may vary as long as they correspond with each other sufficiently to perform location matching operations. Location device 518 may be implemented as any device capable of identifying or determining a current location for mobile computing device 110 at any given moment in time. In one example, location device 518 may be implemented as a global positioning satellite (GPS) system including a GPS transceiver. In another example, location device 518 may be implemented using hardware and/or software arranged to use one or more triangulation techniques capable of triangulating a position based on one or more known coordinates, such as cell data as used in cellular radiotelephone systems, for example. In yet another example, location device 518 may generate current location information from user input, such as entering coordinates or tapping on a map. A user might enter a user command into mobile computing device 110 to “learn” a location, such as entering the user command when at the home or office. The learned locations may be assigned a corresponding name (e.g., home, office, and so forth), and a GUI may allow the user to select the location by name from a drop down menu or other convenient user interface technique. Once mobile computing device 110 generates the location information, location device 518 may output the current location information to alarm manager 504 of OS 502 and/or LBRA 512 directly.

In various embodiments, OS 502 of LBRM 408 may include alarm manager 504. Alarm manager 504 may be coupled to LBRA 512 and location device 518. Alarm manager 504 may manage alarm operations for OS 502 of mobile computing device 110. More particularly, alarm manager 504 may perform location matching operations in order to generate an alarm for LBRM 408. Alternatively, the location matching operations may be performed by LBRA 512 using input received directly from location device 518. An application or user may use alarm manager 504 to set various reminders or alarms. Alarm manager 504 may include, for example, a timer and/or a message interface. Alarm manager 504 may also receive input from location device 518 in the form of current location information. Alarm manager 504 may use the current location information from location device 518, the timer, and/or message interface to send an alarm message when the output of a location matching operation is positive, such as when a target location matches a current location.

LBRA 512 may schedule an alarm to indicate when a target location for a reminder item matches a current location with alarm manager 504. For example, a user may use LBRA 512 and/or alarm manager 504 to set a location based reminder for a certain target location, such as a specific grocery store located at a certain address. Alarm manager 504 may receive current location information for mobile computing device 110 via location device 518. Alarm manager 504 may receive the current location information on a periodic basis, aperiodic basis, continuous basis, request or demand basis, at random intervals, and so forth. A particular frequency controlling when location device 518 provides current location information to alarm manager 504 may vary, but may generally be set based on the size and proximity of the target location. For example, a larger defined target location such as a shopping mall may update the current location less frequently than a smaller defined target location such as a specific office suite. The embodiments are not limited in this context.

Alarm manager 504 may compare the current location with the target location programmed by LBRA 512. In our previous example, when the current location comprises the specific grocery store located at the certain address, thereby signifying a match of the current location with the target location, alarm manager 504 may send an alarm message to LBRA 512 to indicate a need for a location based reminder. In some cases, alarm manager 504 may also send an alarm message to attention manager 506 or display interface 510 thereby directly bypassing LBRA 512.

LBRA 512 may also schedule an alarm to indicate when a target location for a reminder item does not match a current location with alarm manager 504. For example, a user may use LBRA 512 and/or alarm manager 504 to set a location based reminder for a certain target location, such as a work location at a certain address. Alarm manager 504 may receive current location information for mobile computing device 110 via location device 518. Alarm manager 504 may compare the current location with the target location programmed by LBRA 512. When the target location no longer matches the current location, alarm manager 504 may send an alarm message to indicate a need for a location based reminder. In this manner, a user may be reminded of a task when leaving a location, such as picking up grocery items when leaving a work location.

In addition to a target location as a location based reminder trigger, LBRA 512 may also schedule a location based reminder with alarm manager 504 with other reminder triggers. For example, LBRA 512 may schedule a date and/or time as a reminder trigger in addition to the location trigger. In this case, LBRA 512 may record a date and/or time for the alarm in addition to the target location. For example, a user may desire to receive a location based reminder when near a specific grocery store located at the certain address on a certain date and/or time. Alarm manager 504 may perform location matching operations. When alarm manager 504 has a positive match, alarm manager 504 may use the timer to determine a current date and/or time. Alarm manager 504 may compare the current date and/or time with the programmed date and/or time, and if there is a match, then alarm manager 504 may send an alarm message to LBRA 512, attention manager 506, or display interface 510 directly. In another example, LBRA 512 may schedule a distance from the target location as a reminder trigger. LBRA 512 may be used to define a location based reminder distance value, with the location based reminder distance value to define a certain radius or distance surrounding the target location. For example, a user may set a reminder trigger to trigger a location based reminder when within 1 mile of the target location. Any value may be used for the location based reminder distance value as desired for a given reminder item. The embodiments are not limited in this context.

In various embodiments, OS 502 of LBRM 408 may include attention manager 506. Attention manager 506 may be coupled to LBRA 512. Attention manager 506 may provide an attention indicator to attract the attention of a user. The attention indicator may comprise a visual, audible and/or tactile indicator. A visual indicator may include providing visual information on display 104. For example, attention manager 506 may cause a visual indicator such as a blinking symbol or icon to occur somewhere on display 104, such as a highlighted asterisk symbol blinking in the top left hand corner of display 104. Attention manager 506 may be used to indicate that there are messages waiting for review by a user, such as email messages, voicemail messages, text messages, instant messages, and so forth. An audible indicator may include a voice message, tone, ring tone, beep, or some other audible information capable of being reproduced by audio module 412. A tactile indicator may include causing housing 102 to vibrate or pulse.

Attention manager 506 may also be used to provide visual, audible and/or tactile attention indicators to attract the attention of a user and indicate that there are location based reminders to be reviewed by the user. Assume that alarm manager 506 sends an alarm message to LBRA 512 indicating that the current location and/or current date and/or time for mobile computing device 110 matches the target location, date and/or time, and/or location based reminder distance value associated with the reminder item. LBRA 512 may send an attention request message to attention manager 506. Attention manager 506 may receive the attention request message, and provide an attention indicator to display interface 510 and/or display 104 in an attempt to attract the attention of a user.

In various embodiments, OS 502 of LBRM 408 may include user interface 508. User interface 508 may be coupled to LBRA 512 and/or attention manager 506. User interface 508 may be a graphic user interface (GUI) or some other user interface that is capable of conveying information to a user and receiving user commands from a user (e.g., via I/O 416). In response to an attention indicator provided by attention manager 506, a user may use user interface 508 to provide a user command in response to the indicator. For example, if the indicator is a blinking symbol or icon provided in a top left hand corner of display 104, and display 104 is a touch screen display, a user may tap the blinking symbol or icon in order to acknowledge the indicator from attention manager 506. User interface 508 may receive the user command, and send the user command to attention manager 506. Attention manager 506 may generate and send an attention response message to the attention request message provided by LBRA 512, with the attention response message conveying or indicating that a user command has been received.

LBRA 512 may receive the attention response message from attention manager 506, and initiate operations to search reminder database 514 for any reminder items with the relevant target location. LBRA 512 may search reminder database 514 for any reminder items with set location reminder values to accelerate search operations. LBRA 512 may provide a location based reminder for the located reminder items. The location based reminder may comprise a visual location based reminder, an audible location based reminder, or a tactile location based reminder. In one embodiment, for example, LBRA 512 may provide a location based reminder via display interface 510 and/or display 104. The location based reminder may comprise any desired user interface message format and accompanying information. For example, the location based reminder might be a user interface message such as “There are 4 reminder items associated with your current location at address 123 Main Street, Sunnyvale, Calif.” with an accompanying list of the reminder items. A user may use user interface 508 to select a particular reminder item to retrieve further information for a location based reminder, or otherwise processor or handle a given location based reminder.
